VMM: fixed a VERR_SSM_STRUCTURE_MAGIC error when trying to load a saved state made with VBox 4.3.4 when VT-x/AMD-V is disabled. Unfortunately, VBox 4.3.4 produced broken saved states for this configuration so you have to discard these states (bug #12414)

VMM: added a few more MSRs to the whitelist required by certain guests (bug #12245)

E1000: if the cable was disconnected before the guest initialized the device, the link status was not properly set to ´down´ after the initialization completed despite the fact that there was no connection
